Abstract
The utility model relates to a capacitance electroscope which is provided with a disc-shaped base, and a vertical fixing shaft is mounted in the middle of the top surface of the base; a positive pole pointer and a negative pole pointer, which are symmetric, are connected with the fixing shaft through an insulating cover cap; a battery jar for placing a battery is formed in a charging device; a positive pole metal frame and a negative pole metal frame, which are respectively connected with the positive pole and negative pole of the battery, are respectively in upward connection with the two ends of the battery jar; and the positive pole pointer and the negative pole pointer are perfectly inserted into charging slots which are respectively formed at the top ends of the positive pole metal frame and the negative pole metal frame. Therefore, the capacitance electroscope, which can visually detect whether an object is electrified or not and electric property of the object, has a simple structure and remarkable effect.
Description
Technical field
The utility model relates to a kind of electroscope, specifically a kind of condensing type electroscope.
Background technology
At present, electroscope often uses the electrical verification instrument as a kind of physics lesson one's parents, but traditional electroscope can only measure object whether charged and can't measure object electrically, and the experiment equipment cost is higher.
The utility model content
In order to address the above problem, the utility model provides a kind of condensing type electroscope, whether this electroscope not only can be measured object charged, and can measure that it is electrical, simple in structure, easy to use, improved the accuracy of experiment.
The technical scheme that the utility model solves and technical matters adopted is: this condensing type electroscope comprises electroscopic device and charging device; Said electroscopic device has a discoidal base; Vertical stationary shaft is installed in the middle of the end face of said base; Be connected with symmetrical anodal pointer and negative pole pointer through insulating cap on the said stationary shaft; Said charging device has a battery case of placing battery; The two ends of said battery case upwards are connected with cathode metal frame and the negative pole metal frame that is connected with anode and negative pole respectively; The top of said cathode metal frame and negative pole metal frame, being respectively equipped with to coincide inserts the slot of anodal pointer and the charging of negative pole pointer.
The above anodal pointer and negative pole pointer are conductive metal sheet.
The beneficial effect of the utility model is: this condensing type electroscope can measure intuitively the whether charged and object of object electrically, not only simple in structure, and effect is obvious.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Accompanying drawing 1 is the vertical view of the electroscopic device of this condensing type electroscope.
Accompanying drawing 2 is the charging device structural representation of this condensing type electroscope.
Among the figure, 1. base, 2. negative pole pointer, 3. insulating cap, 4. anodal pointer, 5. slot, 6. cathode metal frame, 7. battery case, 8. battery, 9. negative pole metal frame.
Embodiment
In the accompanying drawings, this condensing type electroscope comprises electroscopic device and charging device; Said electroscopic device has a discoidal base 1; Vertical stationary shaft is installed in the middle of the end face of said base 1; Be connected with symmetrical anodal pointer 4 and negative pole pointer 2 through insulating cap 3 on the said stationary shaft; Said charging device has a battery case 7 of placing battery 8; The two ends of said battery case 7 upwards are connected with the cathode metal frame 6 and negative pole metal frame 9 that is connected with battery 8 positive poles and negative pole respectively; The top of said cathode metal frame 6 and negative pole metal frame 9, being respectively equipped with to coincide inserts the slot 5 of anodal pointer 4 and 2 chargings of negative pole pointer.
The above anodal pointer 4 is a conductive metal sheet with negative pole pointer 2.
In Physical Experiment, when needs test positive object whether charged and charged when electrical, this electroscopic device near object under test, if anodal pointer 4 is ostracised is flicked, then the object positively charged; Anodal pointer 4 be attracted near, then electronegative; Anodal pointer 4 near the time electrostatic induction takes place and produce and attract each other, at this moment, only need body to be measured if negative pole pointer 2 is attracted, can to explain that then object under test is not charged near negative pole pointer 2.
When giving anodal pointer 4 with 2 chargings of negative pole pointer; Take off insulating cap 3; Negative pole pointer 2 and anodal pointer 4 are inserted respectively in the slot 5 of negative pole metal frame 9 and cathode metal frame 6, then that two slots 5 are as close as possible but do not contact, utilize battery 8 to they chargings.
